DOOR LOCK.

Application filed July 11,

To fait' lzur/mm. it mat-y cof/warn lie it known that l, frnonrHTonsiionn, a British subject, residing at Edmonton, in the Province otAlberta and Dominion of Can ada, have invented certain new and use iulImprovements in Door Locks, of which the following is speciiication.

The present invention relates to doorlocks or more particularlyknob-locks. It has a very simple and solid construction. It

niay'be applied without change to right or left-hand doors, to thick orthin ones and the combination may be changed without adding or deductingany parts, only by arranging existing ones in different order.

ln the accompanying drawings, one embodiment ot' the invention has beenillustrated and Figure l shows a vertical, longitudinal section ot the'lock assembled in the door,

Figure 2, 3. 4t, 5 and 6 are transverse sections of Fig. l along linesll--ll, III-III, lil-JV, V-V and Vl-VI respectively,

Figure 7 an axial sect-ion along line VII- VII of Fig. l seen fromunderneath,

Figure 8 a bottom plan view of the lett end of the lock barrel,

Figure 9 an elevation of the lock spindle, and

Figure 10 a section on line X-X of Fig. l.

The lock consists ot the following parts: The outer knob 20 and theinner knob 2l which are similar in appearance, are both secured on thelock-barrel 22, the inner knob 21 by means of a screw 23 in the usualmanner, but in order to prevent the outer knob trom being tampered withor removed without authority a. rivet 2i or a split pin having sideprojections ou its shanks` Fig. 2 is used instead. The head of the pinis made. smooth and preferably liush with the surtace of the knob. Thereare provided three or more holes 25 tor this pin or rivet 24, see Fig.S, in order to accommodate diii'erent thicknesses or" the door; in thatmanner the knob 2O will be. held further in or further out on the barrel22. The inner pipe-like ends ot the two knobs are enclosed by thecylindrical hubs 2G ot the escutcheons 27, 28 secured on either side otthe door in the usual manner. The ends of the knobs 20 and 21 abutagainst the shoulders formed at the bottom of the counter bore in thehubs,

in order to prevent axial sliding of the barrel 22 rwith the knobs 20,2l.

ihe outside knob 2() has a central, revoluble button 29 inserted in itsbore and secured by small projections 30 thereon engaging' in an annulargroove 3l provided in said bore to prevent the button from falling out..i longitudinal slit 32 oi the same cross-section as the key'53 isprovided in the center ot' the button 32.

The barrel 22,which is mounted to revolve in the escutcheon hubs 26extends to within a short distance of the outer faces ot the hubs 20, 2land, as has already been described, is rigidlyT secured to them so as torevolve whenever either one of the hubs isturned. rihe outer end of thelbarrel is slotted, longitudinally in two or more places as at 33dove-tail fashion, see Fig. 2. rlhese slots are intended to accommodatethe keyplates, which are preferably made up of a number ot leaves aboutfg inch thick. As shown in Figs. l. and 7 three active leaves Re,engaging the notches 36 in the key 53 are here provided, and a greatnumber of blank leaves serve as lling piecesto properly locate theactive leaves 34. It will easily be understood that an almostunlimitednumber oi combinations can be obtainedby the different arrangement ofthe leaves, without any change in construction of the lock, thusproviding for a great variety of keys. 'In the middle portion ot thebarrel 22 are provided a number oi longitudinal slots 37 torming spacesfor the gear teeth 38 on the shank 39 oi the latch bolt 4:0. The latchbolt, which in this case also constitutes the 'lock-bolt, is preferablymade in two parts as shown in Figa.l 10, that is to say with its head 40threaded on the shank 39. The head 40 is preterably ot square vorrectangular transverse section, bevelled on the non-locking side in theusual manner The middle portion il in order to accommodate a compressionspring 42, which acts between the head 40 outwardly. The inner part 39of the shank iornxs a stop-shoulder thereon yabutting against the collar4-.3 to limit the outward movement of the latch boit. The latter ismounted in a sleeve 4.4 which has a square or rectangular bore toaccommodate the bolt head, as has also the shield plate 4:5. In' thesleeve 4A is provided a stop 46 tolimit 0f the shank is cylindrical anda stationary collar i3 to push the latch ibo inward travel of, the latchbolt. The collar el 4is held in plee@ by means of' one or moresereiwstizfls el?. '.l`he imi/ner side of the sleeve 44 has a cut 4S toaceo'n'iinodate the barrel 22, and its outer end is provided with a hornwhich locks in a corresponding recess in the shield plate 45 to preventit from tornino'. The shield plate 45 is made syninxetriealaround .theaxis ot.' the latch bolt so that it may be reversed and suitable forboth rigiht `and left-hand doors.

The lock spindle '.50 which is about threeters of the length oil? thebarrel 22 is earried in the bore ot the latter and extends from theinner end ot the barrel almost to the sl' l 'for `the key-leayes ltsouter or left 'end .as seen in Fig. l fits the bore of the barrel 22 andhas e shaned slot 3l engaging' e stud threaded inthe barrel 22 forming;a bayonet lock. Both end portions of the run cireuinerentielly on thespindie each extendingfully half-way around while t e middleV orconnecting portion thereof runs longitudinally. The extreme end oi.' thespindle is part y ont awajgf. leav ing` e lng 54 adapted to engage theside of the ley 53, when the latter is inserted to turn the spindle',and a eenter bore provided in the letter to guide the smell tit at theend of the key 53.

rlhe middle portion o'tthe spindle 5() is made smaller in diameter. soas vto clear the t liendend ae seen in the figures is also or theseinereduceddiameter end carries on it. counting from right to lett. thethimble 6. the sto-p ring 57, the compression spring 3S and the 'lockingiliiawl 59. The latter is reroln'ble-on `the spindle and is held by thesp-ringl dagainst the shenlder 60 on the spindle. The other end et thespring abuts a'fainet the stop ring;- :37 which is held se- ,ci l f withthe barrel een by means of one or more screw studs y(il. Vllhelockingpawl 59, which lits loosely in thebore of the barrel 22, projectswith a lug through lor tudinal slot 62 in the barrel, and engages in a4recess 65% provided in the heb 26 of the esfmteheon 2S. so as to beheldfrom turning. e end portion of the inner knobQ] has a. 'pondingslot madelong` enough to ermit the vpewl lu to enter- -it end beeome l renee-swhen it bythe dle 50.

The longitudinal portions of slots 5l and 66 correspond in length to themovement of Athe; loekingpewl .595 in and Vout offengegement with itsseat, the recess 63 in the esrut-eheon hub 26.

he operation oit the lock is as follows, the deer beine' locked and theparts in the relative position as shown in the dilicerent figlires:

The key Tril is first inserted in the knob through the slit 32 in thebutton 29 and made to enter between the leaves 34E, Fig. 2. llAin thetit of the key 53 enters the Central recess the top edge oif the key,which is level with the side of the tit.y will come r the pro]v `,ctinglne' rl"he key is new turned clockwise when after one-quarer turn itwill have the position seen in and 7. that is to say, with ,its fiatside @menging the ir er side ol the lne; 54. After another quarter tern,or e. hell'vtnrn altogether, when it h turned the spindle onequerterturn "he stud 52 sta-nds in the lonnidinal por. on oi? the r'-slot Thekey now upside down to its entering portieri end coiisequently free toslide between the u By pushing; the key' inward, the indle travels withit, thereby disengag- 'ng the parel 59 from its 63, so that, the outerknob 20 may now be turned clockwise. The knob being' secured on thebarrei 22, will cause the latter to revolve, f-rliif'h, l red to thelatch bolt shank 239 will and 'the door will open.

Simultaneously,the longitudinal portion of the .2-slot 5l, 'engaging the stud 52, asal: ready described. will their first pass along; this stud until theletter engages in the left l.; i ciroumi 'en portion ot the .2-slot *iland leek therewiih when the barrel v22 is turned by the knob 20. itinnst, therefore, be evident that the spindle 50 and the pawl rwill Il,l

To lock the7 door when going out the button is turned Vcounter clockwiseas tar as it will go, then drawn out all the way, which will bring thepawl 59 and the spindle 50 both into the right hand or unlockedpositions, so that by a. little morcturning of the button (S5 the lettor outer circumferential portion of the Z-slot 5l will be engaged by thestud 52 andthus hold the pawl out ot the recess (53. lVhen lastly ytheoutside knob 2O is turned counter eloclrwise upon closing the door fromthe outside, the parts will againl means comprising a slidable spindlein ,sa-id barrel.
